What type of proteins assist with moving water through the cell membrane during osmosis?

• A. Carrier proteins
• B. Aquaporins
• C. Receptor proteins
• D. Enzymes

Answer: (B)

Verified step by step guidance

1. Understand that osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
2. Recognize that the cell membrane is selectively permeable and water movement is facilitated by specific proteins.
3. Identify that aquaporins are specialized channel proteins that facilitate the rapid transport of water molecules across the cell membrane.
4. Differentiate aquaporins from other types of proteins such as carrier proteins, receptor proteins, and enzymes, which have different functions.
5. Conclude that aquaporins are the proteins responsible for assisting with the movement of water through the cell membrane during osmosis.
